Abstract: A muscle activity observation apparatus that includes a sensor module and a detection module. The sensor module includes a piezoelectric sensor. Moreover, the piezoelectric sensor has an output that changes in accordance with a tremor of a tendon or a muscle, and an output that changes in accordance with contraction and relaxation of the tendon or the muscle. A detector of the detection module detects an activity state of the tendon or the muscle using a tremor signal and a contraction-relaxation signal output from the piezoelectric sensor.

Abstract: A film-shaped aperture array includes a first principal surface and a second principal surface opposed to each other and a plurality of apertures penetrating the first principal surface and the second principal surface. A projection projecting from the second principal surface in a normal direction of the second principal surface is provided in at least one region in contact with three or more of the plurality of apertures in a part of the second principal surface, when viewed in plan from the normal direction of the second principal surface.

Abstract: A measurement method measures an amount of substance of an analyte in a sample fluid passing through a perforated structure having a pair of principal surfaces opposed to each other and having a plurality of cavity portions extending through both of the principal surfaces. An elapsed time from a time when the sample fluid begins passing through the perforated structure or a predetermined time thereafter to a time when a characteristic value of the perforated structure reaches a predetermined threshold. The elapsed time is used to determine the amount (the concentration) of substance of the analyte.
